./wip/R-entropy, Estimation of Entropy, Mutual Information and Related Quantities

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 1.2.1, Package name: R-entropy-1.2.1, Maintainer: mishka

R implementation of various estimators of entropy, such as the
shrinkage estimator by Hausser and Strimmer, the maximum likelihood
and the Millow-Madow estimator, various Bayesian estimators, and
the Chao-Shen estimator. It also offers an R interface to the NSB
estimator. Furthermore, it provides functions for estimating
Kullback-Leibler divergence, chi2-squared, mutual information, and
chi2-squared statistic of independence. In addition there are
functions for discretizing continuous random variables.

Log message:
Update R-entropy to version 1.2.0.

             CHANGES IN `entropy' PACKAGE VERSION 1.2.0

* new functions KL.plugin(), KL.empirical(), Kl.Dirichlet(), and 
  KL.shrink() for computing the Kullback-Leibler divergence.
* new functions chi2.plugin(), chi2.empirical(), chi2.Dirichlet(), and
  chi2.shrink() for computing the chi-squared statistic.
* new functions chi2indep.plugin(), chi2indep.empirical(), 
  chi2indep.Dirichlet(), and chi2indep.shrink() for computing the 
  chi-squared statistic of independence.
* new discretize2d() function for simple binning of a pair of random
  variables.
* in all shrinkage functions the target option has been removed (and
  the default uniform target is now always used).
 
             CHANGES IN `entropy' PACKAGE VERSION 1.1.9

* new discretize() function for simple binning of a continuous random
  variable.
* now requires R >= 2.15.1.

             CHANGES IN `entropy' PACKAGE VERSION 1.1.8

* License file removed.
* Dependencies updated.
* the functions freqs.shrink(), entropy.shrink(), mi.shrink(), 
  entropy(), and freqs() now allow to specify the shrinkage intensity.

Log message:
Oops, new entropy package has been released a week ago - update.

Major changes:
* small in documentation file fixed (for R 2.13.0 release)
* added in documentation that the default unit for the entropy
  is "nats" (natural units), for "bits" one needs to set \ 
unit="log2".
